thanks CC. the upside is that I'll just have to ride the new american classic wheels with the continental supersonic tires. i didn't intend to use them for training rides, but my choices are put the old bontrager tires back on, ride the american classics, or not ride at all.

I'll take them to Derek later in the week and see if he can show me how to do it.

Whoops! thought of another option....I could ride the old bike. See another reason to have more than one bike.
